CLAMP FOR CONVEYING APPARATUS- SPEGIFICA'IION forming part of LettersPatent No. 760,7 7 1', dated May 24, 1904. Application filed June1,1903. Serial No. 159,462. (No modem To all whom; it may concern: I

Be it known that I, GEORGE A. AMSDEN, of

Springfield, in the county of Hampden and State. of Massachusetts, haveinvented certain new anduseful Improvements in Clamps for ConveyingApparatus, of which the following is a specification. My inventionrelates to new and useful improvements in conveying apparatus; and itsobject is to produce an improved clamp by which telegrams or sheets ofpaper or other articles of a similar character are automatically pickedup at stations and automatically discharged at other stations.

The apparatus comprises an upper and a lower track, between which runs acarrier propelled by a continuously-running cord or 1 cable, andon saidcarrier is carried the improved clamping device which forms thesubject-matter of this invention, which automatically picks up andautomatically discharges the objects carried to and from definitepoints. The automatic pick-up and discharge and the propulsion of thecarrier are substantially similarjto that shown in Patent No. 718,185,dated January 13, 1903, issued to the Lamson Consolidated Store ServiceCompany, of Newark, New Jersey, as my assignee.

My invention consists of certain novel features of construction in aclamp device hereinafter described.

In the drawing the figure is a perspective view of an improved clamp andcooperating parts.

The upper and lower channel-tracks A and B are supported by suitablebrackets A, and between said tracks runs the carrier C, propelled bycontinuously-running cable in a manner substantially similar to thatshown in the above-mentioned patent. To said carrier is secured theplate D, providedwith two outwardly-extending lugs J, which form ahearing for the shaft H. On saidshaft is rigidly mounted the arm G,formed integral with the upwardly-extending arm L, on the upper end ofwhich is a suitable roller L. Also around said shaft is a spring I,secured at K in the arm G and at its opposite end bearing on the upperend of the lug J.

The clamp consists of an upper member E and a lower member F, formed asshown.

The upper member extends out from the plate D through the lugs J and isprovided at its center with a substantially right-angle pro-- the twomembers of the clamp the same can- 1 not slip out, owing to theprojections E E, F, and E the same holding the articles firmly in place,the projection E having a downward pressure on the center of thetelegrams or other articles. The roller L, as shown in the drawing, willengage the switch M, opening the clamp to allow the discharge of thetelegrams, and continuing will be opened by another switch, similarlyplaced to the switch M, to pick up telegrams, &c. This opening forpicking up and for releasing articles is' similar to that shown in theabove-mentioned patentand forms nopart of the present invention. I donot limit myself to the arrangement and construction shown, as the samemay be Varied Without departing from the spirit of my invention. v

Having thus described the nature of my invention and set forth aconstruction embodying the same, What I claim as new, and desire tosecure by Letters Patent of the United States, is

In an apparatus of the character described, a clamp consisting of anupper fixed member and a lower spring-controlled member, the uppermember having an intermediate projection and projections at itsextremity at an angle thereto, and a lower member having a sideprojection at an angle thereto.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 18th day of May, A. D. 1903.
